Tech notes: Red Bull's floor row unravelled

Controversy clouded Red Bull's victory in Monaco when rival teams questioned the legality of small vents fitted to the floor at the rear of the RB8. Craig Scarborough explains why the row flared up and how the 'holes' work

Controversy was again sparked around the Red Bulls legality at Monaco. Several teams were unhappy with the detail of the RB8's floor and sought clarification from the FIA, although no formal protest was lodged.

The entire issue revolves around small vents the team have fitted to the floor ahead of the rear tyres. According to the technical regulations, these must not be enclosed holes.
